Seaweeds are a major contributor to global marine aquaculture production, with the biomass being mainly used, among others, for human nutrition, pharmaceutics, and cosmetics. However, green seaweeds are severely underrepresented, compared to red and brown macroalgae. Caulerpa lentillifera (known as “sea grapes” or “green caviar”) is an edible, green seaweed with a distinctive texture and various nutritional benefits. In this review, all articles on sea grapes published between 1900 and October 2022 and found in the scientific citation databases Scopus and Web of Science (search string: “caulerpa” AND “lentillifera”) were grouped by research topic and the intended application following the PRISMA approach. 51% of the 130 articles included in the review focused on the topic of “Biochemical composition”, followed by “Water treatment” (18%) and “Ecophysiology” (15%). The most prominent application was “Pharmaceutics”, followed by “Cultivation” and “Fundamental research”. In order to provide a knowledge base to researchers and practitioners of C. lentillifera aquaculture, research that was simultaneously grouped under one of the topics “Biochemical composition”, “Water treatment”, or “Ecophysiology” and the applications “Cultivation”, “Nutritional value” or “Post-harvest” was summarized in more detail. Light management of sea grapes, their use as a high-value co-culture species and the capacity to bioremediate nutrients, as well as their short shelf-life were identified as important areas of research interest. The assessment revealed several knowledge gaps, for example the need for intra-species comparisons of C. lentillifera biochemical composition across spatial and temporal scales.

海藻是全球海水养殖生产的主要贡献者，其生物质主要用于人类营养、药品和化妆品等领域。然而，与红色和棕色大型藻类相比，绿色海藻的代表性严重不足。细叶藻（被称为“海葡萄”或“绿色鱼子酱”）是一种可食用的绿色海藻，具有独特的质地和多种营养价值。在这篇综述中，所有在 1900 年至 2022 年 10 月期间发表并在科学引文数据库 Scopus 和 Web of Science 中找到的有关海葡萄的文章（搜索字符串：“caulerpa”和“lentillifera”）均按研究主题和预期应用进行分组，如下所示： PRISMA 方法。评论中收录的 130 篇文章中，51% 的主题集中在“生化成分”，其次是“水处理”（18%）和“生态生理学”（15%）。最突出的应用是“药剂学”，其次是“栽培”和“基础研究”。为了向 C. lentillifera 水产养殖的研究人员和从业者提供知识库，同时对“生化成分”、“水处理”或“生态生理学”主题之一以及“栽培”、“营养价值”或“收获后”应用进行了更详细的总结。海葡萄的光照管理、其作为高价值共培养物种的用途、生物修复营养物质的能力以及其较短的保质期被确定为重要的研究兴趣领域。评估揭示了一些知识差距，例如需要进行物种内比较 以及它们的保质期短被确定为重要的研究兴趣领域。评估揭示了一些知识差距，例如需要进行物种内比较 以及它们的保质期短被确定为重要的研究兴趣领域。评估揭示了一些知识差距，例如需要进行物种内比较C. lentillifera跨空间和时间尺度的生化成分。
